Can a miner's hashrate be derived from shares submitted at a given difficulty?

0

Trying to generate useful stats about client activity in a pool. If a quantity of submitted (timestamped) shares is known, and the difficulty of each share is known, how can the client's aggregate hashrate be determined?

hashes = shares * share_difficulty * 2**48 / 65535

thus:

megahash_per_second = shares_per_second * share_difficulty * 4295.032833

Conceptually: Compute the expected number of hashes required to find each share that is actually found and sum them. Divide by the amount of time to get the hash rate. – David Schwartz – 2013-09-18T23:24:45.303
